Struct rustracing_jaeger::span::SpanContextStateBuilder

pub struct SpanContextStateBuilder { /* private fields */ }

SpanContextState builder.

Normally it is recommended to build SpanContextState using APIs provided by Tracer or SpanContext rather than via this.

But it may be useful, for example, if you want to handle custom carrier formats that are not defined in the OpenTracing specification.
